Entropy Generation in Three Dimensional Flow of Dissipative Fluid

Abstract

Theoretical analysis of entropy generation in three dimensional boundary layer flow over a bidirectional exponentially stretching surface in the presence of viscous dissipation is performed. By taking suitable similarity transformations governing partial differential equations are reduced to ordinary differential equations. Expressions for entropy generation and Bejan number are also obtained via similarity transformations. The obtained self-similar equations are solved numerically using shooting scheme. The impact of flow controlling parameters on velocity components, temperature distribution, entropy generation number and Bejan number are analyzed and discussed graphically in detail. The novelty of the present study is in the entropy analysis of three dimensional boundary layer flow and in heat transfer analysis in the presence of viscous dissipation.
